they are not meant to do 7000+ RPM What i've heard that missfire has many reasons. 1. coil packs 2. Spark plug 3. Air leak Please mention more you think can be
hehehe, thats no misfire but the rev limiter kicking in...btw, don't do that too often, you can grenade your engine fairly easily, my car doesn't misifire but there the occasional backfire since the free flow, it occurs at 3000-3500rpm
I like that back fire my car does when I let the car go down hill in 3rd gear and no accelrater pushed car sounds like.. bood bood bood.. pataaakkkk!! hahhahah
